Abstract

The invention belongs to collophanite flotation technology, and relates to a direct flotation collector of collophanite at room temperature and a preparation method thereof. The collector comprises ingredients with the following weight ratio: fatty acids 95-100 parts, sodium hydroxide 10-15 parts, sodium dodecyl sulfate 3-8 parts, polyoxyethylene5-10 parts and pine oil 1-3 parts. The preparation method includes: according to a certain weight ratio, heating and stirring the mixture of sodium dodecyl sulfate, polyoxyethylene pine oil, and water to obtain a novel surfactant; subjecting the fatty acid to saponification; finally, compounding the saponificated fatty acid and the novel surfactant by a certain percentage, stirring uniformly so as to obtain the collector. The direct flotation collector is not only good in solubility, but adaptable to low and medium grade collophanite and different temperature. In addition, the direct flotation collector has the advantages of good stability and simple pharmaceutical preparation process, Information about residual glue in the glue container is determined according to forming of vacuum when the vacuum generating system extracts air in the detection tube and accordingly can be widely used in the beneficiation of collophanite.

Description

technical field [0001] The invention belongs to the collophosite flotation technology, in particular to a preparation method of a normal-temperature positive flotation collector for collophanite. Background technique [0002] Phosphate rock resource is an important non-metallic mineral resource and a strategic mineral resource related to my country's food security and national stability. my country's collophosite accounts for 85% of the total reserves of phosphate rock, and most of them are low-grade ores. Except for a few rich ores that can be directly used as raw materials for high-concentration phosphorus compound fertilizers, most of the phosphate rock must be enriched by ore dressing before it can be produced. Meet the production requirements of phosphoric acid and high-concentration phosphate fertilizer. Therefore, collophosite beneficiation plays a pivotal role in the development of phosphate rock. [0003] The useful minerals in most collophosites in my country are ...
